Can someone explain the relationship between the two? Specifically is it better to use an OPT whose wattage rating is greater than the output power of the amplifier? What would happen if you use an OPT rated at 120 watts in an amplifier rated at 200 watts?

we have to live with the reality of things.....but then again, OPT's can be designed to any spec if one wishes, those are Dynaco offerings and considered as very good at the time....Patrick Turner has an excellent exposition re OPT's in his website, read it carefully and you will understand why...

reason is that the OPT primary inductance drops as frequency decreases...OPT design is more of an art than science...a compromise as characteristics are working against each other.....Norman Crowhurst has written many fine articles about OPT's....
